Abstract: PURPOSE:To prevent penetrating phenomenon from resulting, and to stop easily etching at the face of a thin capacitor insulating film when capacitor electrode material is patterned, by constituting a three-layer structure in which the capacitor electrode material of a polycrystalline silicon film is put between metal or metal silicide films such as high-melting-point films. CONSTITUTION:After a molybdenum silicide film 5, a polycrystalline silicon film 6 with impurities diffused therein and a tungsten film 7 are sequentially deposited, a resist film 8 is patterned only over regions for a desired capacitor to be formed. Next, using the resist film 8 as a mask, the tungsten film 7 is etched by reactive etching employing Cl2 gas. Thereafter, the polycrystalline silicon film 6 is photo-etched, and at this time the etching is stopped at the face of the molybdenum silicide film 5. After the molybdenum silicide film 5 is removed, by using the same mask, an inter-layer insulating film 9 is formed. After a gate oxide film 10, gate electrode 11, N-type impurity diffusion layers 12, 13 are formed and an insulating film is last formed, Al wiring 16 is formed through a contact hole 15 formed by reactive ion etching.

IPC: B29L31/34
Filed: 1984-05-09
Abstract: PURPOSE:To improve workability remarkable in assembling mold parts and demounting a mold by using shape memory alloy in assembling mold parts. CONSTITUTION:The jig for fixing the top and the bottom force is designed to store the dimension and shape required when the top and the bottom force 2, 1, are clamped by preheat through the head 13a of the fixing piece 13 not to leak synthetic resin from between those forces. The cup fixing jig 15 is designed to store the dimension and shape required when the injection hole cup 4 is stuck by preheating tightly to the cup fixing piece 14. The dimension and shape that have been stored in advance by preheating are changed and the top and the bottom force are clamped to each other not to leak synthetic resin from between the forces. The injection hole cup 4 also is set by the cup fixing jig 15 in the same way. If the forces 1, 2 are cooled all over the surfaces, the fixing jig 12 for the top and the bottom force and the cup fixing jig 15 that have been provided by the shape memory alloy return automatically to the initial shapes and dimensions to enable the top and the bottom force 2, 1 and the injection cup 4 to be demounted.

Abstract: PURPOSE: To improve yield and quality of a fine device of dissolution wafer process, and increase the degree of freedom of design, by arranging an etching control seal around the periphery of fine structure. CONSTITUTION: An etching control seal 20 whose both surfaces are surrounded by trenches 22 and 24 surrounds fine structure 12 and the periphery of the whole part of a trench 14 defining the fine structure 12 and stretches. The seal 20 is provided with a flat ring which rises to the upside of the left part of a surface 11 of a substrate 10 which is much doped as far as the same degree as the rising region 16 of the fine structure 12.
